When I received this glass mat I was disappointed because the packaging had been penetrated through by, what I assumed to be a forklift. I thought for sure it would be damaged. However, it was not affected at all! Not a scratch. Considering the damage to the packaging, I would say this glass mat holds true to the manufacturers discription of strength and scratch resistance. Very pleased about this because I am actually using this as a table top cover so it had to be in excellent condition!
